Abstract
This work aimed to design the structure of molded pulp with bi-wave cushioning and test the cushioning performance. Two different groups of the cushioning samples were designed, processed and prepared, group A with same the height of 30 mm and varying wave angles of 5°, 15° and 30°, respectively, while group B with the same wave angle of 5° and varying heights of 10, 20 and 30 mm, respectively. The performance was tested by static compression, dynamic impact and vibration tests. The maximum loads of group A samples with 30 mm height and 5°, 15° and 30°, were 1230, 1430 and 1600 N, respectively, while those of group B samples with 5° and 20, 30 mm height were 560 and 1380 N, respectively. The maximum loads became lager with increasing wave angle at constant height, and with increasing height at constant wave angle. The dynamic impact test showed that the height and wave angle impacted the cushioning application scope of the structure, and the result of vibration test proved that the profiled structure molded pulp could completely be used for highway transportation.
